Students should be exposed to current and interesting data sets. Most, if not all, will have at least some familiarity with The Biggest Loser television show making this activity a great example of using real-world data.
Although it is clearly possible for two people to share a birthday, our experiences (and intuition) inform us that it is more likely that two people will have different birthdays. That is to say, the probability of a shared birthday between two people is close to zero. However, the chance of a shared birthday may increase if a larger group of people is considered.
(Grades 6–12+) Originally published in February 2017, this lesson focuses on correlation as a way of measuring the strength and direction of a linear association between two numerical variables.
(Grades 9-12+) Originally published November 2015, this lesson engages students in an exploration activity and a class discussion. After completing this lesson, students will be able to determine when events are mutually exclusive, and then use the Addition Principle to calculate the probability of mutually exclusive and non-mutually exclusive events.
